Fair call, promotion wasn't the best word. What I meant to say was, they give her airtime without criticism - I'd say that's a form of support, for a similar reason to your concern about giving her attention. Even if we're talking about cases where the reporting is neutral, factual and with minimal bias, it's still selected and reported on regularly, and that shapes the worldview of the audience, especially if the heavily-flawed ideas Hanson espouses aren't addressed in the reporting. Repeating their messages verbatim through a megaphone is spreading their ideas - outlets almost never do the same with open neo-Nazis' speeches, for obvious reasons.

And as is common knowledge, there are additionally some mass media favourably promoting PHON, like Sky News, who have already called this event a "failed stunt" (lol)
